Since Scenic Sites, heritages to protect the value of landscapes, include valleys and mountains, the cultural heritage protection zones and historical and cultural environments preservation districts are designated extensively. So the landscape protection effects of the designation of scenic sites should be examined. Accordingly, the purpose of this research is to present the methods of efficient institution of district for landscape protection of scenic sites. As the research subject, Cheongamjeong Pavilion and Seokcheongyegok Valley in Bonghwa (Scenic Site No. 60), which has the highest designation rate, was selected. The results of this research using the cumulative visibility technique of GIS are as follows. First, the method of selecting the viewpoint by preparing the reverse cumulative visibility from important landscape resources of the valley was presented. The reverse cumulative visibility can be utilized for rational selection of the viewpoint with regard to scenic sites. Second, the landscape analysis method in consideration of human viewing angle and the visibility of the background of landscape resources was developed. Third, the hierarchical landscape protection method of scenic sites utilizing cumulative visibility was presented. Fourth, it was established through on-site inspections that the method of institution of district is the practical method.

This study aimed to develop epoxy putty as a multi-purpose connection and restoration material that can be used for material-specific restoration work such as metal, wood, ceramics, earthenware and stone artifacts by replacing synthetic resins currently being used for preservation treatment of cultural assets. Existing synthetic resins have the issue of cutting force resulting from high strength, deflection resulting from long hardening time, contaminating the surface of artifacts through staining on tools or gloves and need for re-treatment resulting from material discoloration. Accordingly, paste type restoration material most widely being used in the field of cultural assets preservation treatment was selected and examined the property to select it as an object of comparison. Based on such process, epoxy putty was developed according to the kind of agent, hardener and filler. For the purpose of solving the issues of existing material and allowing the epoxy putty developed to have similar property, property experiments were conducted by selecting agents and hardeners with different characteristics and conditions. The study findings showed that both kinds are paste type that improved work convenience and deflection issue as a result of their work time of within 5~10 minutes that are about 3~10 times shorter than that of existing material. In regards to wear rate for increasing cutting force, it improved by about 3 times, thereby allowing easy molding. For the purpose of improving the issue of surface contamination that occurs during work process, talc and micro-ballon were added as filler to reduce the issue of stickiness and staining on hand. Furthermore, a multi-purpose restoration material with low shrinkage, low discoloration and high cutting force was developed with excellent coloring, lightweight and cutting force features.

Actual vegetation map drown with the scale 1 to 100 and Alnus japonica population in Ja-neup and Woong-neup of the Mujechi moor were described in order to monitor long-termly and preserve permanently, where is a very rare Molinietea moor and a legally protected area. A total of 3036 plots of 5m $\times$ 5m were surveyed during summer 1996. Thiessen polygons of 1491 alder trees were derived from the plot data. Actual vegetation map was illustrated by 6 cover types such as needle spike-rush type, moor-grass type, alder-moor type, eulalia type, oak forest type, and exposed site. Molinia grasses native to the moor and Miscanthus grasses alien to the moor are reciprocally dominant. The area of Molinia grasslands was rapidly in decline and alder population size was dramatically in increase in the moor, particularly in Woong-neup. In Molinietea moor preservation more attention should be focused on the regulation of a nutrient rich soil from forest road and fire.

Outdoor cultural buildings and their accessories receive different amounts of solar radiation depending on their location's latitude, azimuth, and tilt. Shading is also affected by the surrounding terrain and objects, necessitating individual and quantitative shading analysis. In July 2019, this study conducted a shading analysis on the tops, midpoints, and bottoms of wooden pillars in the azimuth of Cheongpunggak, a traditional building in South Korea's National Research Institute of Cultural Heritage. The shading analysis found that the solar access/shade predicted by the solar trajectory meter was 30 minutes slower than measured in the field. The highest solar access and solar radiation levels came from the south, followed by the west, east, and north. The pillars' bases received the highest solar access and solar radiation, followed by their midpoints and tops. Solar access was high at tilt 90°, but solar radiation was high at tilt 0°, due to the light-collection efficiency and the irradiance. Shading on the pillars' tops was caused by the roof eaves, while shading on the midpoints and bases were affected by the surrounding pillars, topography, and other objects. Simultaneous solar access at the tops, midpoints, and bottoms was possible for 365 days for the northwest, west, and southwest pillars but only from October to March for the south and southeast pillars.

1953년 7월 27일 정전협정 이후 한반도를 가로지르는 DMZ (Demilitarized zone: 비무장지대)가 설정되었다. DMZ에 출입은 군사정전위원회의 허가가 있어야 가능하기에 군사시설 및 군작전지역을 포함하여 DMZ 및 민간인통제선 이북은 민간인 접근의 제한으로, 단절된 공간으로 변모하였다. DMZ는 우리나라의 대표적인 동고서저의 지형 및 다양한 생태환경을 두루 갖추고 있어 중요한 생태적 요충지로 평가받고 있다. 산림지역은 민간인통제지역까지 합치면 40여개의 산지가 분포하고 있으며, 하천은 크게 15개의 크고 작은 하천이 위치하고 있다. 남방한계선 수계를 따라 일부지역들은 하천 배후습지, 묵논습지 등 습원형태로도 많이 발견되고 있다. 이런 습원지역들은 대부분 미확인 지뢰지대로 접근이 제한적인 만큼 지난 세월의 흔적들을 고스란히 담고 있다. 1965년 한국자연보존연구회는 30여명의 국내학자를 동원하여 서울에서 가까운 DMZ 인접지역에 대한 예비적인 학술조사를 실시하였으며, 이를 계기로 1966년 10월부터 1968년 9월까지 2년간에 걸쳐 한국자연보존위원회 34명의 국내학자와 미국 스미소니언연구소(Smithsonian Institution) H. K. Buechner 박사를 대표로 5명의 국외학자가 공동으로 종합적인 학술조사를 수행하였다. 이는 DMZ 연구의 시작을 알렸으며, 이후 남북관계나 시대여건에 맞추어 간헐적으로 다양한 조사 및 연구들이 이어져오고 있다. 2015년부터 2018년까지 DMZ 철책주변 현장조사를 통해 확인된 식물현황은 964분류군이다. 군시설로 인해 식물서식환경이 제한적인 상황이지만 척박한 환경에 적응하고 있는 식물은 다양하다. DMZ와 맞닿아 있는 7개 지역에 대한 식물현황은 철원 638분류군, 연천 631분류군, 양구 525분류군 순으로 나타났다. 대부분 중동부 지역에 높은 식물종수가 나타났으며, 서부와 동부의 식물들이 고르게 나타나는 결과로 보인다. 큰잎쓴풀, 봉래꼬리풀 등 희귀식물도 있는 반면, 잠재적으로 생태계에 영향을 줄 수 있는 침입외래식물도 다수 포함되어 있어서, 지속적인 모니터링 및 관리가 필요하다. 그 중에서도 양구지역에 새롭게 발견된 Macleaya cordata (Willd.) R.Br.(양귀비과)는 독성이 포함된 식물이며, 인제에서 2014년에 발견된 미역취아재비는 DMZ일원에 제한적으로 분포하는 종이였으나 현재 연천에서 발견되는 등 확산에 대한 관리방안이 필요하다.

Changes in a society and visual media has a tight relationship. Photography represented the last 20th century in the visual media; while the 21st century we live in is represented by moving image(video). The change of visual media also brought changes to the archaeological recordings. As information is gathered from the field work in archaeology, it seems that use of video recording, a reliable way of collecting and recording data, will increase. The process of archaeological excavations can be considered as a contents itself. Also, video recording has many advantages when recording environmental surrounding of the sites and artifacts, for the reservation of the scenery, and as recorded heritage of the humankind. Video recording can be a tool of conversion to public archaeology to devote to its social and academic roles. Considering all of the above, studying ways to record and preserve visual materials is essential in the field of archaeology and we should be prepared for it. We strongly propose reinstatement of the visual archaeology, which should be studied in archaeological perspective. The direction of the study of visual archaeology can be summarized into two. First is the study on the video recording during field work and the archive of video recordings. Second is the study on the media as the tool of communication. More detailed and organized research should be considered in depth in the archaeological theory and methods.

This study investigated the initial behavior (flowability and setting properties) and shrinkage characteristics of lime mortar, based on the mixing ratio of hydrated lime (lump, powder) and commercial lime, which is primarily used for repairing and restoring cultural assets. The flowability showed that the optimum mixing water contents of the masonry lime mortar were 8-10% for the lump hydrated lime, 10-18% for the powdered hydrated lime, and 17-40% for the commercial hydrated lime. The results of the setting and shrinkage analysis showed that the average final setting time ratio compared to the standard of cultural asset repair was in the increasing order of commercial hydrated lime(0.4) < powder hydrated lime(5.6) < lump hydrated lime(5.7). Moreover, the average shrinkage ratio was ordered as lump hydrated lime(1.1) < powder hydrated lime(1.2) < commercial hydrated lime(3.0). The analysis of the physical and chemical characteristics of hydrated lime showed that the optimum mixing water content was reduced as the particle size of the lime increased, thus delaying the setting time and decreasing the length change rate (shrinkage). These results are expected to contribute to the prediction of the initial behavior and shrinkage characteristics of mortars using handmade and commercial lime during repair and restoration work on cultural, heritage buildings.

As part of open science, the government adopts a national research data sharing and utilization strategy, forms a governance system at the national level, and promotes policies for research institutes to implement. Although the policy for managing research data is carried out centering on the academic world, it is insufficient compared to developed countries, and even this is a reality in which researchers do not have enough awareness to introduce it to the field. The purpose of this study is to understand the research data management status of researchers in each academic field. Academic fields consisted of four fields including Library and Information Science, Statistics, Ecology, and Korean Musicology, and the current status of data management was identified through a survey. The current status of research data management was analyzed from the perspective of research data production, sharing and management, saving, preservation and reuse. As a result of the study, it was found that there were differences by discipline in terms of data production, data sharing and management, data preservation, and data reuse, except for data savings.

Living culture emphasizes cultural activities in daily life based on local characteristics, and aims to integrate art with daily life to communicate with others through activities of local residents. In this process, the values that individuals and society should have, are evoked and restored. In order to understand the context and processes in which the values of the living culture are expressed as local culture, we analyzed the case of 'Gosaek Nongak(community band music, dance and rituals in Korea) conservation association' in Suwon area and tried to diagnose how art and daily life are integrated and restoring community life in the actual field. For this purpose, phenomenological research was conducted through literature review participatory observation, and in-depth interviews to categorize the social impacts of living culture activities and public support due to individual, community, and local influences. We found that public support for living culture led to increased artistic development and human interaction in the community, and that individuals who are thus empowered to seek artistic experience and actively interact with other people, emerge as vital subjects and practitioners of culture and arts in their local community. Furthermore, we found that the activities of living culture facilitated the formation of local identity for members and local residents. Through living culture activities, members and local residents became more aware of being members of the community and found value and meaning in participating in daily life and cultural activities.

It is necessary to recycle and reuse waste paper for preservation of the global environment. Instead of a solid deinking agent, liquid deinking agents have been made using various fatty acids with EO/PO added for higher deinking effect. The removal efficiency of ink on waste paper was evaluated by the ERIC and brightness properties after processes of recycling pulping (sample composition ONP: OMG = 5:5, concentration 15%, temperature $45^{\circ}C$, pulping time 20 min.) and flotation (concentration 1%, temperature $45^{\circ}C$, air flow 7 L/min, time 8 min.). Also, the ink reattachment of paper was evaluated by hyperwashing. The results show that it is effective for mass-preparation to saponify oleic acid with KOH at $80^{\circ}C$ and to add EO/PO. This deinking agent was used in a paper plant, and we evaluated the brightness, color, and ERIC. The deinking agent showed excellent performance.
